I appreciate the correction. I continue to distrust blockchain.com wallet the more, I even thought the quote above will be genuine, after the article was written by them, they are lying. I believe it is noncustodial, but I do not fully believe again, what if they can be able to access the encrypted data? I believe if they are the one that encrypt it, they can also have malacious ways not known to others about the decryption. Although, they are the wallet that are fixated at the old standard, not even supporting segwit since it was implemented some years ago.
